The only minor inconvenient is that the hotel is on a third floor without elevator (but, anyway, you´re only going to your room once per day, maximum twice, don´t you?).
Appart from that, everything is perfect. You have a cute and clean room where you can find everything you need, cleaned everyday, of course.
The staff is more than friendly; specially Francesco, who was the guy that received us at our arrival, and who spent a lot of time talking with us about restaurants, monuments, secret places, etc. to visit in Rome.
For the price you pay, is an excellent option. You have two subway stops near the hotel (5 minutes walking), you have a daily breakfast included in the restaurant placed below the hotel (basic breakfast that you can turn into a continental breakfast paying just 5 euros).
To sum it up, great option if you´re travelling to Rome.
